Just ":set tabstop=4" in vi, for example. If your system doesn't define the POSIX.1 ssize_t data type, then delete the appropriate #ifdef/#endif lines at the beginning of "ourhdr.h". If your system's doesn't define the variables for getopt(), then delete the appropriate #ifdef/#endif lines at the beginning of "ourhdr.h". If your system doesn't support send() and recv() (e.g., OSF/1) then delete the appropriate #ifdef/#endif lines at the beginning of "ourhdr.h".
